(Nanowerk Spotlight) All mechanical systems exhibit vibrational resonances, where energy transmission through the structure spikes at certain natural frequencies. This resonance effect stems from the ...

In science and engineering, it's unusual for innovation to come in one fell swoop. It's more often a painstaking plod through which the extraordinary gradually becomes ordinary. But we may be at an ...

In the sporting goods sector, consumers are willing to invest heavily in materials that combine both performance and sustainability. The Alliance for European Flax-Linen and Hemp, has reported an ...

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs ...

A collaboration between the University at Buffalo School of Engineering and Applied Sciences and the U.S. Air Force Research Lab (AFRL) has shown it’s possible to electronically tune the frequency ...

Shown below is the influence of the damping ratio on the free response of the single-DOF system for the range of the damping ratio from zero to one. Note how quickly the free response dies away for ...
